Are there standard advertising banner sizes?

Question

I'm designing a new site and for the first time I want to incorporate 3rd party advertising. I haven't chosen an advertising partner yet.

Are there standard banner sizes I should be designing for?

Answer 1

Most advertising agencies stick to a pseudo-standard for banner sizes.

You can find them here. In case that link ever goes dead, the most common in use are (in px):

• 486x60 (Full Banner)
• 397x72 (Navigation)
• 120x240 (Vertical Banner)
• 120x90 (Button)
• 120x60 (Button)
• 88x31 (Micro Button)
• 234x60 (Half Banner)
• 160x600 (Vertical Tower)
• 125x125 (Square)
